SPECIFICATION formingpart of Letters Patent No. 670,517, dated March 26,19 01.

Application filed January 20, 1900. Serial No. 2,199. (No model.)

To all whom it may conceive.-

Be it known that I, GEORGE H. Ross, a citizen of the United States,residing at Canton,

in the county of Stark and State of Ohio, have invented certain new anduseful Improvements in Attachments for Lamp-Burners; and I herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the annexed drawings, making a part ofthis specification, and to the figures of reference marked thereon, inwhich- Figure l is a side elevation showing a portion of the lamp-body.Fig. 2 is a detached view of the connecting thimble or band. Fig. 3 is alongitudinal vertical section. Fig. 4 is a transverse section throughline X X, Fig. 1, except that the section is taken at right angles tosaid line.

The present invention has relation to attachments for lamp-burners; andit consists in the different parts and combination of parts hereinafterdescribed, and particularly pointed out in the claim.

Similar numbers of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, 1 represents the burner proper, which maybe of the form shown ,or it may be of any other desired form,

. inasmuch as the burner proper forms no particular part of the presentinvention, except that a burner of some kind must necessarily be used tocarry out the purposes hereinafter described. 7

The ordinary screw-threaded flange 2 of the burner l is attached to theband or thimble 3 by means of suitable screw-threads 4, formed upon theinner periphery of said band or thimble, as illustrated in Fig. 2, andsaid band or thimble 3, connected to the flange 5, which flange isconnected to the lamp-body 6 in the usual manner. The screw threads 7are formed upon the outer periphery of the connecting-baud 3, saidscrew-threads being for the purpose of connecti'ngsaid band-to theordinary screw-thread flange 5, connected to an ordinary lamp-body 6. v

For the purpose of providing a safetylampor, in other words, providingfor the escape of any gas that may accumulate in provided with theapertures 8, which apertures are located directly opposite each other,as illustrated in the drawings, and are for the purpose above stated andfor the additional purpose of allowing air to pass through saidapertures, and thereby produce better combustion.

It will be understood that by my improved device all danger ofexplosions is done away with by reason of providing means for the rapidescape of accumulated gas from the lam p-body proper or from the vesselcontaining the fuel from which the light is fed.

It will be understood that when the band or thimble 3 is placed inproper position upon the burner 1 the apertures 8 should come oppositethe fiat sides of the wick 9, and in order to accomplish this theconvolutions of the screw-threads 4, formed upon the inner periphery ofthe band or thimble 3, should end directly above one of the apertures 8,as illustrated at X, Fig. 2. By this arrangement the band or thimble 3can be turned until it comes to a dead stop, and when brought to a deadstop the apertures will be in proper position with reference to the wick9, or, in other words, with reference to the Wick passage or tube formedin the burner.

I have illustrated two apertures such as 8; but it will be understoodthat a single aperture maybe used and the same object accomplished; butI prefer to provide the thimble or band 3 with the two aperturesillustrated and located as shown.

The convolutions of the screw threads formed upon the inner periphery ofthe collar terminate so that the rotation of the ring or thimble 3 willbe stopped at a point so as to locate the aperture or apertures formedin the ring directly opposite the flat side'sof the wick.

Having fully described my invention, what I claim, and desire to secureby Letters Patout, is-

The combination of a lamp burner provided with a screw-threaded collar,a band or thimble formed of uniform diameter throughout its entirelength, and provided with screwthreads upon its outer and innerperipheries,

an aperture formed in the band and'between i the convolutions of thescrew-threads, and

the lamp-body 6the screw-thread band 3 is 1 the screw-threads upon theinner periphery of the band terminating at a point opposite I Intestimony that l claim the above have the aperture located between theSGIGW- hereunto subscribed my name in the presthreads and theserewthreads upon the colence of two Witnesses.
